HAIR-PIN.

Specification of Letters Patent.

Patented Nov. 8, 1917.

Application filed January 11, 1917. Serial No. 141,745.

To all whom it may concern:

Be it known that I, MANUEL D. AVILLAR, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new anduseful Improvements in Hair-Pins, of which the following is a specification.

This invention relates to a hair pin of novel construction, which obtains a firm grip upon the hair, and is not apt to become dislodged, during automobiling, gymnastics, or other more or less violent exercises.

In the accompanying drawing:

Figure 1 is a perspective View of a hair pin embodying my invention;

Fig. 2, a front View, and

Fig. 3, a side view.

The two shanks 1 of the hair pin are intertwisted at their upper or converging ends to form an integral curved bistranded neck 2. At the end of this neck, the two strands again separate to form an integral elongated loop 3, the two sides of which face or overlie shanks 1, for some distance, and converge into a tapering point 4, which is centered between the shanks.

Shanks 1 are straight at their lower ends, and corrugated at their upper ends, the corrugations 5, extending backwardly and forwardly, i. 6. toward and away from loop 3. This loop is likewise corrugated, back- Wardly and forwardly, its corrugations 6 being arranged in substantial parallelism with those of the shanks.

When the hair pin is inserted, a strand of hair, will be tightly grasped between the corrugations of the shanks and the loop, while the intertwisted neck 2 possesses such superior tension that it will effectively hold the device in position and prevent its dislodgment even under severe strain.

I claim:

A hair pin comprising a pair of corrugated shanks, a curved intertwisted neck, and a corrugated loop which overlies said shanks, the corrugations of said loop extending in substantial parallelism with the corrugations of the shanks.

MANUEL D. AVILLAR.
